Instructions
- Preheat the oven to 425 F. Line a standard muffin pan with muffin liners.
- Place the blueberries in a small bowl and toss with a few teaspoons of flour.
- In a medium mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In another medium mixing bowl, whisk together the butter, eggs, sugar, buttermilk, vanilla extract, and lemon zest.
- Fold the flour mixture into the wet ingredients and stir to combine with a wooden spoon or silicone spatula.
- Add the blueberries, stirring carefully to incorporate.
- Make the streusel topping: in a small bowl, combine the oats, flour, and brown sugar and stir to combine. Using your fingertips, work the butter into the dry ingredients until incorporated – the mixture should be chunky without any dry bits of flour remaining in the bottom of the bowl.
- Fill the muffin cups nearly to the top of the liner, and top with a spoonful of streusel topping.
- Bake for 5 minutes at 425 F, then reduce the oven temperature to 375 F and bake for an additional 15-17 minutes, or until muffins are golden brown.
- Allow muffins to cool completely in the pan before enjoying.
